Nutrafol®, Viviscal®, and Folexin® are the three most-recognized hair growth supplements on the market. All three have published clinical evidence; all three are sold widely on Amazon Prime. For GLP-1 users dealing with the rapid-weight-loss shedding affecting 40-60% on Ozempic®, Wegovy®, Mounjaro®, or Zepbound®, picking the right one matters because hair recovery takes 6+ months. This guide breaks down the three directly.

The 5 picks
1. Nutrafol — best comprehensive formula
Saw palmetto + ashwagandha + marine collagen + tocotrienols + curcumin + biotin. 4 caps/day. ~$88/month.
Nutrafol has the strongest published evidence per dollar (Ablon 2018: 35% hair density increase at 6 months). Comprehensive multi-mechanism formula. Most-prescribed by dermatologists. Premium-tier price.

2. Viviscal — best-published single mechanism
AminoMar® marine complex + biotin + zinc + vitamin C. 2 tablets/day. ~$40/month.
Viviscal has decades of clinical evidence on the AminoMar marine complex. Less comprehensive than Nutrafol but tested in more RCTs. Mid-tier price; cheaper monthly cost than Nutrafol.

3. Folexin — best DHT focus
Saw palmetto + biotin + fo-ti + folic acid + zinc + horsetail. 2 caps/day. ~$25/month.
Folexin has the strongest saw palmetto content per dollar (DHT-blocker focus). Useful for male users with combined GLP-1 telogen effluvium + androgenetic alopecia. Cheapest of the three; less broadly-validated formula.

4. Cost over 6 months
Nutrafol: $528. Viviscal: $240. Folexin: $150.
For a 6-month recovery protocol: Nutrafol is $378 more than Folexin. Question is whether Nutrafol's broader formula + stronger published evidence justifies the premium for your specific shedding pattern.

5. Best for women vs men vs combined
Women + telogen effluvium primary: Nutrafol Women. Men + AGA + telogen effluvium: Nutrafol Men or Folexin. Budget users: Folexin or Viviscal Original.
Match formula to physiology. Female GLP-1 users with primarily diffuse shedding: Nutrafol Women has the most-direct RCT evidence. Male users with combined pattern + telogen loss: Folexin's saw palmetto content matters.

Frequently Asked Questions
Which works fastest for GLP-1 shedding?
No supplement works fast — hair recovery is biologically slow (6+ months minimum). Differences between Nutrafol/Viviscal/Folexin are at the margin. Consistency over time matters more than which one.
Is Nutrafol really worth 3x the price of Folexin?
Strongest published evidence: yes for users with active diffuse shedding. For users wanting basic DHT-blocker support: Folexin's saw palmetto delivers most of that effect at 1/3 the price.
Can I stack two of these?
Not typically recommended — overlapping ingredients (saw palmetto especially) can double-dose. If stacking: low-dose Viviscal + Folexin's saw palmetto, but check ingredient overlap.
Will any of these stop my Wegovy hair loss completely?
No supplement stops telogen effluvium completely — once a follicle is shed, it sheds. These accelerate regrowth + protect not-yet-shed follicles. Combine with LLLT + adequate protein + minoxidil for best results.
Safe to take with my GLP-1?
Yes — no interaction with semaglutide, tirzepatide, retatrutide. Take with food for GI tolerance during GLP-1 titration.
How long before I see results?
Reduced shedding: 6-10 weeks. New visible growth: 12-16 weeks. Meaningful density: 6 months. All three brands follow similar timelines.
